Does A Successful Operation Long Jump Turn WW2?

"They shot Churchill. let's fold."

Or, "Let's burn their cities and sow the earth with salt."

the second metaphorically isn't that outside the box; fdr's murder in particular would stir up anger in the us exceeding pearl harbor...i could certainly see smothering berlin in anthrax as a measure considerd quite seriously
 
I think as it's 1943, The Reich will lose ultimately, however do we for example have the A-bombings in Japan under the new US administration?

I think the nuclear bombing of Japan would still happened.

Almost any American president would try to burn two or three Japanese cities before sending hundred of thousand of his compatriots to fight and possibly die ...

In those days nukes were just a "very big bomb", nothing less, nothing more.

EDIT: Maybe they warn them before, but the Japanese would have not believe them
